  • Such an electric drive unit can serve as the sole drive source for a motor vehicle (pure electric drive on one axle).
  • a drive unit may be provided in support of a main drive unit, in particular supportive of an internal combustion engine (hybrid drive).
  • the electric machine is designed, for example, as a three-phase asynchronous motor or as a permanent magnet synchronous machine.
  • a rotor of the electric machine can drive an input element of an axle differential gear, wherein, if required, a transmission gearbox can additionally be provided between the electric machine and the axle differential gear in order to translate the rotational speed of the rotor of the electric machine into the low gear.
  • an electric drive unit with the features of claim 1, and in particular by the fact that the lubrication and cooling circuit comprises an aqueous lubricant, which is guided at least through an interior of the electric machine to parts of the electric machine in the interior cool.
  • the electric drive unit thus comprises a lubrication and cooling circuit with an aqueous lubricant, i. a mixture of water and at least one other substance (e.g., an alcohol).
  • the aqueous lubricant may comprise a water-glycol mixture.
  • the water content of the lubricant is used for particularly effective cooling of the interior of the electric machine.
  • the aqueous lubricant is guided in the interior of the electrical machine along parts of the interior.
  • the waste heat of the electric machine can be particularly effectively absorbed and removed, in particular in combination with cooling and the outside of the electric machine, since the waste heat is mainly produced in the interior of the electric machine.
  • the aqueous lubricant may lubricate the interior of the electric machine (e.g., bearings of the electric machine).
  • Water has a high heat capacity, a high thermal conductivity and a correspondingly high heat transfer coefficient compared to a typical lubricating oil.
  • the aqueous lubricant can absorb and dissipate a comparatively large heat output of the electric machine.
  • no special requirements to be placed on the heat transfer surfaces so that in a simple and compact construction of the electric drive unit, a high power density of the electric machine can be achieved, i. a high efficiency.
  • the aqueous lubricant along an inner circumferential surface of a stator of the electric machine is guided.
  • the aqueous lubricant can be guided past the winding ends of the electrical machine in order to absorb and dissipate a high heat output.

  • the cooling water of said cooling circuit for the inverter can be performed in an advantageous development along parts of the electric machine to assist there cooling, in particular on the outside of the electric machine, for example along an outer circumferential surface of a stator of the electric machine.
  • the said cooling circuit can thereby additionally form an outer cooling jacket for the electrical machine.
  • the drive unit comprises an inverter electrically upstream of the electric machine, wherein the aqueous lubricant of the lubrication and cooling circuit is also guided along parts of the inverter in order to cool it.

  • the drive unit further comprises a transmission mechanically coupled to an output of the electric machine (eg rotor), the aqueous lubricant of the lubrication and cooling circuit not only cooling the interior of the electric machine, but also along parts of the transmission to cool and lubricate the transmission.
  • a transmission is an axle differential gear, which is coupled on the input side with the electric machine, optionally via an additional transmission gear.
  • the transmission coupled to the electric machine can be a planetary gear or a stationary gearbox.
  • the aqueous lubricant has a low electrical conductivity such that a continuous flow of electrical current through at least one bearing of the electrical machine is made possible.
  • a low electrical conductivity of the aqueous lubricant (caused by the structural design of the electric machine) electrical current is continuously allowed, which flows through the storage of the electric machine (corresponding to a reduced internal resistance of the bearing itself).
  • electrical discharges in the bearing and thus the destruction of the bearing surfaces are prevented.
  • the lubricating and cooling circuit of the electric drive unit may further comprise a heat exchanger over which the aqueous lubricant releases heat to the environment.
  • this heat exchanger may comprise cooling fins on an outside of the housing in order to release waste heat from the aqueous lubricant to the ambient air by heat-conducting connection.
  • Fig. 1 shows a first embodiment of an electric drive unit for a motor vehicle, comprising a lubricating and cooling circuit 11, which contains an aqueous lubricant, ie a water-based lubricant.
  • the electric drive unit comprises a cooling circuit 13 which contains cooling water and is operated at a lower temperature level than the lubrication and cooling circuit 11.
  • the electric drive unit is preferably an axle drive unit and comprises an electric machine, for example a three-phase Asynchronous motor or a permanent magnet synchronous machine, and coupled to an output of the electric machine transmission.
  • the lubricating and cooling circuit 11 with the aqueous lubricant is used for cooling and lubricating parts of the electrical Engine and the transmission, while the cooling circuit 13 is used in addition to the cooling of parts of the electric machine and an associated electrical switching device. This will be explained in detail below.
  • the lubricating and cooling circuit 11 with the aqueous lubricant comprises a lubricant conveyor 15 which continuously circulates the aqueous lubricant in the lubricating and cooling circuit 11.
  • the aqueous lubricant is passed along portions of the interior 17 of the electric machine, preferably at least over the coil ends.
  • the aqueous lubricant in the interior 17 of the electric machine can be guided along an inner circumferential surface of the stator of the electric machine and / or along an outer circumferential surface of the rotor and / or through axial and / or radial cooling channels of the rotor of the electric machine.
  • the aqueous lubricant absorbs the substantial part of the waste heat of the electric machine.
  • it is of particular advantage that due to the water base of the aqueous lubricant, a high efficiency of heat dissipation is achieved, since the water content has a high heat capacity and a high thermal conductivity.
  • the thus heated aqueous lubricant is supplied to a lubricant / cooling water heat exchanger, namely the high-temperature side 19 of the heat exchanger. About this is absorbed by the interior 17 of the electric machine waste heat to the cooling circuit 13.
  • the thus cooled aqueous lubricant is then supplied to parts of a transmission 21 of the electric drive unit, for example, the tribological contact surfaces and bearings of a axle differential. Thereafter, the aqueous lubricant is taken up again by the lubricant feed unit 15, wherein, for example, between the gear 21 and the lubricant conveyor 15, a lubricant sump may be provided (not shown).
  • the cooling circuit 13 includes for the cooling water contained therein own cooling water conveyor 23. This first conveys the cooling water to a cooling water ambient air heat exchanger 25, which emits the waste heat contained in the cooling water to the ambient air 27, for example via cooling fins or cooling fins. The thus cooled cooling water is then guided along an electrical switching device of the electric drive unit, for example along an inverter 29. After the inverter 29, the cooling water along the low temperature side 31 of the aforementioned lubricant / cooling water heat exchanger is performed to waste heat from the lubrication and cooling circuit 11 record. Finally, the cooling water of the cooling circuit 13 is also used to cool an outer side 33 of the electric machine, for example a cooling jacket, which surrounds or forms the outer circumferential surface of the stator of the electrical machine. Finally, the cooling water is fed back to the cooling water conveyor 23, optionally via a sump.

  • Another advantage of the embodiment according to Fig. 1 is that the aqueous lubricant of the lubrication and cooling circuit 11 also serves to lubricate parts of the transmission 21, so that no additional lubrication circuit is required for this purpose.
  • a separate cooling circuit 13 ensures that for the electrical machine associated switching device (inverter 29) reliably a low temperature level is maintained in order to protect the electrical switching device from overheating.
  • the heat dissipation performance for the electric machine is further increased because in addition the (cooler) outer side 33 of the electric machine is cooled.
  • Fig. 2 shows one opposite Fig. 1 simplified embodiment of an electric drive unit comprising only a lubricating and cooling circuit 11 with an aqueous lubricant, ie no additional cooling circuit 13 with pure cooling water.
  • a lubricant conveyor 15 is provided. This first conveys the aqueous lubricant to a lubricant / ambient air heat exchanger 35, from which the waste heat contained in the aqueous lubricant is released to the ambient air 27. The thus cooled aqueous lubricant is then, ie at the lowest temperature level, guided along an electrical switching device in the form of an inverter 29 to cool it. Thereafter, the aqueous lubricant is guided along the outside 33 of the electric machine (eg cooling jacket on the outer circumferential surface of the stator).

From there, the aqueous lubricant is sucked in by the lubricant delivery device 15 and pumped again in the direction of the heat exchanger 35. Between the gear 21 and the lubricant conveyor 15, a lubricant sump can be provided, which can serve in particular as an additional heat exchanger for discharging heat to the ambient air 27.
  • a particular advantage of the embodiment according to Fig. 2 In turn, the use of an aqueous lubricant, which is guided through the interior 17 of the electric machine, results in a particularly efficient dissipation of the waste heat, thereby enabling a high power density of the electrical machine.
  • only a single circuit 11 is provided. This is made possible in particular by supplying the aqueous lubricant to the different cooling points in the order of the respective desired temperature level, ie beginning at the inverter 29 (lowest temperature level) via the outside 33 of the electric machine to the interior 17 of the electric machine (highest temperature level ).
  • Fig. 3 shows one opposite Fig. 2 once again simplified embodiment of an electric drive unit.
